I stayed at P Residence for 2 weeks. It's a great location, about 2 minutes' walk from the cafes and restaurants of Thong Lor.
The building and the apartment are on the older side, but it's quiet, spacious and convenient. There's a comfortable L-shaped sofa, a decent kitchen and very effective AC throughout. A great spot if you're working remotely online while travelling. I'd happily stay again.
